Dental crowns are a cosmetic and restorative tool used in dentistry to cover cracked and chipped teeth, and are also useful for maintaining the structural integrity of a damaged tooth.
In simple words a dental crown is a small cap or helmet that covers a damaged tooth. It helps to restore the shape and look of the tooth and stops the chips and cracks from getting worse. Dental crowns can be also used to restore a tooth as part of a dental implant. The crown sets on top of the implant as the final stage of the process. Dental crowns can be made of porcelain, a composite material or metal alloys such as gold.
The Process For Dental Crowns
To begin the process is indispensable to polish some of the enamel from the tooth to make room for the crown. After that is going to be needed an impression of your teeth to design the crown and make sure that crown fits well, this can be done with mould making material or digital scanning technology. The crown can be made in a lab by an expert technician and can take a few days to be done. Therefore, maybe you have to make two trips to the dentist, one for the preparation and another to establish the restoration.
Another option to make dental crowns is with the help of a milling machine such as the CEREC machine. These use digital mouth scans and digitally tooth designs to precisely shape the restoration in a special machine. These crowns are then ready to be placed on the same day as your initial visit.
Once the crown has been manufactured it will be attached to the tooth.
The Alternatives to Crowns
Inlays and onlays are almost comparable to crowns but these do not fix the whole crown of the tooth. Inlays fix the dips in teeth and onlays fix the pointed parts of teeth.
The inlays and onlays require a process identical as a full crown but can take less time to make the restoration and usually have a lower cost.
